Ok, I am getting throttle closures from boost/load overshooting target all over the place. What can be done about this?

I don't think we have a solution at this time (ATR). Assuming it is due to hardware (stiff wastegates) and can't be optimized with OTS tune.

Also, I mostly see people posting single gear cool night logs. I rarely get timing drops on a single or two gear pulls, but if I let it heat soak and push it with multiple-gear pulls (ex 3-4-5), I am likely to get timing drops on fifth gear. Is that acceptable?
